9. It had been agreed that Theo would send 300 francs a month (150 francs for each), in three 100-franc instalments. It is most likely that Theo reverted to the system that he and Vincent had used earlier for three monthly payments (starting in June 1882;
see letter 234). This meant that Vincent usually received his allowance in instalments arriving around the 1st, 11th and 21st of every month, though sometimes a payment was deferred. Theo thus sent money three times a month in November and December 1888. See also Dorn
